Replacing 302 with a 351

I have a tired 302 motor with an aluminum intake and headers. Will my intake and headers bolt up to a 351 Winsdor.

Nope the intake on a 351 is wider than a 302. The headers will prolly bolt up to the heads but I don't know how the rest of the fitment would be. It may give you some issues. just my 2 cents. Good luck with the swap!

the headers will work but require some Y pipe work. most shops can do that easy and cheap. what are you doing the swap in? and what tranny is being used

It also depends on how the headers tuck inbetween the frame rails. This is a concern to watch out for.
